Tips from the Community
There are two ways to get up to the Subway Cave: one is easier, but goes along a narrow cliff. The more direct approach is more technical, going up the direct slope, but also less scary if you're not good with heights.

The Subway Cave is a remarkable slot-like natural rock formation and is often considered a "secret spot" due to its location; however, you will likely encounter plenty of other visitors here. Reaching this location requires a short scramble, but the breathtaking views of the surrounding red rock landscape make it well worth the effort.

The Lava River Cave is a massive lava tube deep within the Coconino National Forest. You can access and explore the cave on your own. Expect some scrambling over big boulders, some ducking in lower sections and cool temperatures within the cave. Bring at least two sources of light as it it pitch dark and you cannot find you way out of the tunnels without light. The tunnel has a length of almost a mile! The cave was discovered in 1915.

Entrance to the cave is pretty straight forward; you will arrive at the back of the cave once you walk up the small rock walkway. If you wish to view the ruins, keep to the right ledge and walk straight out of the cave. The ruins are still in good condition, but do not touch them or run your hands over the rock walls!
